Many forms of cancer, such as prostate, breast, and colon cancer, can run in families. Patients with afflicted relatives often request screening, and they look to us for guidance.
A 72-year-old white man whose father died from prostate cancer had the following prostate-specific antigen (PSA) values: 1.2 ng/mL in December 1996, 1.4 ng/mL in July 1997, 1.6 ng/mL in May 1998, 1.6 ng/mL in October 1998, and 1.9 ng/mL in March 1999. At the patient's request, because of the rise in PSA levels, urological consultation was obtained, and adenocarcinoma of the prostate (Gleason score, 6) was subsequently diagnosed.
